Answer:

The correct answer is OPTION C (Circumduction)

Explanation:

Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.

Explain why scientirsts concluded that the instructions for species characteristics were carried in DNA.
siniylev [52]

Answer:

Explanation:

Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.

DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.

Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.
